DEVICE FOR SETTING LAClNG-STUDS.

SPECIFICATION forming part of Letters Patent No. 329,264, dated October27, 1885.

Application filed Ann 29, 1885.-

To all whom it maylconcern:

Be it known that I, MELLEN BRAY, of N ewton, in the county of Middlesexand State of Massachusetts, haveinvented certain new and usefulImprovements in Devices for Setting Lacing-Studs, of which thefollowing, taken in connection with the accompanying drawings, is aspecification.

My invention relates to devices for setting lacing-studs, and isdesigned more especially for setting glove-lace studs provided with aconcavo-eonvex washer, such as is described in another application ofmine filed in the Patent Office at \Vashi'ngton, District of Columbia,February 14, 1885, and numbered 155, 870; and it consists in certainnovel constructions, arrangements, and combinations of parts, which willbe best understood by reference to the description of the drawings, andto the claimsv to be hereinafter given.

Figure 1 of the drawings is a side elevation of the stud-setting machineembodying my invent-ion. Fig. 2 is acentral vertical section of aportion of the machine through the axis of the setting-tools in positionfor commencing the setting, with the stud to be set and its washer inposition to be acted upon by the descending setting-plunger. Fig. 3 is asimilar section of the lower setting-tool with the work thereon and. thestud completely set. Fig. 4 is a plan of the lower setting-tool with thework removed, and Fig. 5 is a front elevation of the same.

scale.

In the drawings, A is the base of the machine, from which rises thegoose-neck A, carrying in its end the setting-plunger B, arranged to bemoved upward by a spring, (not shown,) and to be depressed by the leverO, to which motion is imparted by the rod D and a. treadle-lever, (notshown,) to which the lower end of said rod is connected, all of which isold and of well-known construction, my present invention being confinedto the setting-tools and the means employed to facilitate the insertionof the stud into the pocket for receiving it. In the base of themachine, and in axial line with the setting-plunger B, is set theanvil-socket a, inwhich is fitted the steel anvil b, having its upperend cupped out to fit the convex outer surface of the stud-head, andarsenal No. 163,808. (No model.)

ranged to be slightly adjusted in its socket by means of the screw 0, asshown in Figs 2 and 3. The anvil-socket a has formed upon its upper ,endthe collar a, to which is fitted the cylindrical sleeve (1, provided atits upper end with the outwardly-projecting collar d, and at its lowerend with the inwardly-projecting annular lip d which fits to the body ofthe anvilsooket below the collar (6, as shown in Figs. 2 and 8. Theupper end of the sleeved has formed therein a shallow dovetailed groove,in which is fitted a thin steel plate, 6, in the upper face of which isformed the annular curved bottomed recess 6, having an inner diameterabout equal to the diameter of the base-collar of the stud f to be set,said plate having a portion of its front edge cut away to theinnerperiphery of said recess, as shown at e"in Fig. 4, in order that thestud to ,be set may he slipped upon said plate fill its base-collarrests upon its upper surface, with its center or axis concentric withsaid annular recess 6, while the outer head of the stud is beneath theplate e and resting in the concave end of the anvil b, as shown in Figs.2 and 8. The plate 6 is made of a thickness just equal to the desireddistance between the outer head and the base-collar of the stud, and thesleeve (1 is forced downward, so as to clamp the outer head of the studf between the cupped end of the anvil b and the under side of the plate6 by the tension of the coiled spring 9, surrounding the body of theanvil-socket a between its collar a and the annular lip d of the sleeved, as shown in Figs. 2 and 3.

In order to place the stud f upon the plate 6 in the proper position tobe set, the sleeve d and plate e must be lifted against the tension ofthe spring g, which may be done by pressing upon the rear end of thelever E, pivoted at h to the goose-neck A, and having its front. endforked, so as to engage with the collar 01 upon two opposite sides ofsaid sleeve. The upper end of the sleeve d has a recess, d, formed inits front side to facilitate the insertion of the stud to its properposition upon the plate 6 and its removal after being set. By thisconstruction and arrangement of the anvil and its accessories forholding the stud in position thereon a solid bearing for the stud isobtained to receive the blow of the clinching-tool, the outer surface ofthe head resting in the cupped upper end of the anvil b, and the platefilling the space between said head and the base-collar, so that whenthe 5 blow ot'theclinching-ttml isgivcn tothe shank '0! therivettoclinch it the blow istmnsinitted through 'Lhcstnd -'to the anvil 6, nostraiii'being applied to the plate 0, except a crushing strain.

to Heretofore, as far as I know, in setting studs having solid heads thewhole strain of clinch:

ing the shank of the stud-and that a tensile strain-has been received bythe plate which entered between the outer head and the basecollar, whichhas been found to be objectionable, particularly when setting studsdesigned to be used with a lacingcord of small size, as

i for glove-laeings, for the reason that the plate could not be madesullicient-ly strong to resist the strainfor any considerable time,which objection is entirely overcome by my inventiou. Another advantageof this arrangement is that if from any cause the space between theouter head and base-collar of the stud is too great, the act of settingthe stud reduces said space to the required standard dimension, anduniform with all the studs set upon the same plate.

. It is obvious that a thicker or thinner plate may be substituted forthe plate 0 shown in the drawings. according to the size and style ofstud to beset, with which change and a proper adjustment of theauvil bby the screw I I 0 my improvement, so far as described, is adapted toset the ordinary tubular-shanked lacing-stud; but in order to facilitatethe setting of my improved glove-lace hook or stud with itsconeavoconvex washer. which forms the subject-matter ofanotherapplication, tiled 40 February 14, ISSI, Serial No. 155,870, 1attar-h to the-clinchingtooli the sleeve j, ar ranged to surround andproject below the lower end of the clinching-tool i, and to be movedupward thereon against the tension of the spring 7:, said sleeve beingguided in its vertical movennaits'aml prevented from thin ing upon itsaxis by the pins 1 l, projecting radially from the enlarged part of theclinchingtool ithronglrslots m m, cut through the o walls of the sleevej, all as shown in Fig. 2.

hen the stud has been placed in position-' upon the plate 0 with itsshank upward. and the material in which the stud is to be set and theconcavo convex washer n are placed upon the shank as shown in Fig. 2,ifthe settingplunger be moved downward, the sleeve j first comes incontact with the washer u and forces it downward into close contact withthe material and the material' into close contact with the base-collar,and by virtue of the concave form of the side of the washer n,which isnext to the material, the material is bent down around said base-collarand into the annular recess 0', as shown in Fig. 2, and then theclinching-tool i descends and clinches the shank over upon said washer,while the sleeve j remains stationary.

When it is desired to set studs without the eoncavomnvex washer, theannular recess 1' may be dispensed with, the plate r having its upperside made a plain tlat surface like its under side. u

What I claim as new. and desire to secure by Letters Patent of thet'nited States, is-

1. Asameans forholdingalacing-studwhile being set and receiving the blowofthe settingtool, a stationary anvil having its upper end shaped to fitthe outer surface of the head of the lacing-stud, in combination with aplate arranged above said anvil and adapted to till the space betweenthe outer head and the basecollar of the stud to be set. and a springarranged to act upon and pros said plate toward said anvil to clamp thehead of the stud between it and said anvil, so that the shock of theblow of the clinching-plunger shall be transmitted to the stationaryanvil instead of being received and sustained by said plate,substantially s described.

2. The combination of a stationary anvil havingits upper surface shapedto fit the outer siirfircc ofthe outer hcadof the stud to be set, aslecve-surrouinling said anvil, a removable 'plate secured-to andextending across the top of said sleeve and arranged to till the spacebetween said outer head and the base-collar of said stud, and aspringarmnged to press said sleeve and plate downward so as to clamp thehead of the stud between said plate and anvil, substantially asdescribed.

3. The combination of the stationary anvil a b, the sleeve d, arrangedto surround the anvil, and provided with the recess (1, the plate4-,sccured to the upper end of the sleeve (Land provided with therecess!" and the notch v, and the spring all armnged and adapted tooperate substantially as and for the purposes descrilwd.

4; The combination of the anvil a b, the sleeve d, provided with thecollar (l'.the plate (secured to said sleeve, the spring and the lever1'], all arranged and adapted to operate substantially as described.

5. The combination of the anvil a I). the sleeve 1!, the plate 0, thespring g, the clinching-tool i, the sleeve j, and the spring A, andmechanisnnas described,for imparting to said clinching-tool areciprocating motion, substunt iall y as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
